When the main warranty of the car is gone you still get warranty on the parts and service you pay for out of pocket, from BMW's perspective the cost of the "performance mode" is amortized beyond the initial warranty period too. We also see this in other things too you have differential pricing in say electronics and electronic components too, sure some of it is binning but not only quite often the "enterprise" tax is just the fact that these parts will be run longer and under more stress so their MTF is different. An HDD in a home computer will be under very different loads than one in a NAS. And quite often there aren't many physical differences between the drives in some of the lower end models there are no differences at all and in some cases non-NAS drives might actually be "better" than their lower-end NAS counterparts. What you are paying for when buying a WD RED isn't necessarily a more durable drive, you are essentially paying a premium for future warranty claims, it's essentially an insurance scheme in which WD RED NAS drives are defined as higher risk than say their Black or Blue series.
